+*Rails 3.2.0 (unreleased)*
+
+* Active Record's dynamic finder will now raise the error if you passing in less number of arguments than what you call in method signature.
+
+ So if you were doing this and expecting the second argument to be nil:
+
+ User.find_by_username_and_group("sikachu")
+
+ You'll now get `ArgumentError: wrong number of arguments (1 for 2).` You'll then have to do this:
+
+ User.find_by_username_and_group("sikachu", nil)
+
+ [Prem Sichanugrist]
+
*Rails 3.1.0 (unreleased)*
* ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature.
